Ok I am now installing Ubuntu and I'll try on that one. About your library, it doesn't compile the "decnumberxx_test.xcodeproj" because it can't find the "cstdint" library... Do you maybe have a clue about what this error is and how to make it work? It's actually quite strange because I tried on another project to include "cstdint" and it all worked well... ----- Federico Pirovano -- View this message in context: http://gcc.1065356.n5.nabble.com/Problems-with-decimal-decimal-header-on-OS-X-tp902209p902256.html Sent from the gcc - Help mailing list archive at Nabble.com.
